KLUBERLECTRIC KR 44-22

Special grease for the lubrication of electrical switches, contacts and sensors.

Klüberlectric KR 44-22 is a special grease for the lubrication of electrical switches, contacts and sensors. It consists of a synthetic hydrocarbon oil and lithium soap incorporating a UV indicator enabling quality inspection when locally applied in small quantities. A special additive combination makes Klüberlectric KR 44-22 particularly suitable for the lubrication of electrical components. It is intended especially for the protection and lubrication of copper, tin and silver surfaces against corrosion. Further positive effects are: reduction of plug-in and switching forces, reduction of fretted oxide development, extended connecting and switching cycles, constantly low contact resistance and smoother switching transitions.

For electrical components in the automotive, industrial engineering and installations sector. Due to its low base oil viscosity, Klüberlectric KR 44-22 works particularly well under low contact forces and at low temperatures. It is compatible with most plastic materials and hence can be used for the lubrication of plastic/plastic material combinations. Klüberlectric KR 44-22 minimises contact resistance values under lifetime operating requirements subject to varying electrical and mechanical loads.
To utilise this special grease's full performance capacity, component parts to be greased should be cleaned to remove all foreign substances such as corrosion protection oils, waxes, etc. Electrical contacts should be bright and clean.
The lubricant can be applied by spatula, tampon printing or via automatic dosing equipment. Due to the many different material compositions, in terms of elastomers and plastics, compatibility with the selected materials should always be tested prior to series application.

For low-temperature applications
Good corrosion protection of copper and silver contacts
Ageing and oxidation stability
Good compatibility with plastics
Contains a UV indicator
